Mid/rear Seats Assembly problems of the 2011 Chevrolet Malibu

For sometime now in the past few years when I get into the driver seat it feels like the seat is shifting to the right. The issue was felt but has gotten worse as time went on. I do know that there was a recall on the drivers seat belt and I'm not sure if that's what caused the problem as I after 1-2 years went to the back seat to the rear of the seat and put my hands under the lower right hand side of the seat and lifted. The seat moved! I then called Chevrolet to see if they has problems with the seat or the frame and I was told no. I then talked with mcdermott and I was told the seat would cost me close to $1,000 dollars. I then contacted cna national warranty corporation and I have bumper to bumper coverage through the extended warranty. Cna is refusing to cover the seat frame but would cover the seat track. I called Chevrolet again on 03/27/2017 and they told me because it was out of warranty they wouldn't cover the seat? this is the first time in my life I have dealt with a driver seat breaking on a Chevrolet product. I weigh 200lbs and the seat frame shouldn't have broken. What would happen to this seat if there was an accident and movement from a human body with a seat belt? I have a case number from Chevrolet: 2844719955. I'm working on getting a case number from cna today. I have also read about the 2006, 2010, 2011 and 2012 Malibu issues with car seats. I need the seat replaced and it has done some damage to the center console from the movement from the seat. This a serious safety issue that Chevrolet and cna is refusing to fix.

I did have a recall on the front seat belts, not sure if the seats were removed. Since then the drivers seat felt as if it was closer to the center console and leaning more to the right not to mention a tool (battery powered angle driver) was found in the back left seat later and returned to mcdermott. My seat is leaning more and more as time passes and I went to the rear seat to look at the drivers seat and the right side mounted to the floor rail is lifting up? I the spoke with Chevrolet direct online and was told it was out of warranty. I have an extended warranty but this is a huge safety issue. Can you imagine if I was to get into an accident and me the seat with my seat belt on went through the windshield. This issue needs to be fixed and my seat is also damaged from the movement, leather seat. That needs to be replaced.
